Until 1 April 2002, replacement windows and doors
are not subject to building control or inspection by council appointed
officers. The new regulations require all installations to meet
improved insulation standards and a certificate must be issued by
building control officers for every installation.
As there are up to 1.2 million installations (£
1.4 billion value) per year, it would be an impossible task for
building control officers to check all installations. A new scheme
has been initiated which allows the hard-stretched officers to concentrate
on new building work, whilst ensuring that installations comply
The replacement window industry has set up a self-certifying
scheme known as FENSA (Fenestration Self-Assessment Scheme) and
is designed to relieve the otherwise massive pressure on the resources
of Building Control Departments.
The object of FENSA is to regulate installers and
to self-certify their installations and remove the need for individual
installations to be inspected by local building control officers.
